1. A data scheduling method, being applicable to a base station, wherein the method comprises:
sending a scheduling instruction to a terminal, wherein the scheduling instruction is used for indicating to the terminal whether to transmit a same data packet on a plurality of frequency-domain resources of an unlicensed frequency band; and
when the scheduling instruction indicates to the terminal to transmit the same data packet on the plurality of frequency-domain resources, receiving the same data packet transmitted by the terminal on at least one frequency-domain resource among the plurality of frequency-domain resources, wherein receiving the same data packet transmitted by the terminal on at least one frequency-domain resource among the plurality of frequency-domain resources comprises:
detecting at least one frequency-domain resource among the plurality of frequency-domain resources;
determining idle frequency-domain resources among the at least one frequency-domain resource detected; and
receiving the same data packet on at least one of the idle frequency-domain resources,
wherein the receiving the same data packet on the at least one of the idle frequency-domain resources comprises:
selecting one or more idle frequency-domain resources among the idle frequency-domain resources based on a preset parameter to transmit the same data packet,
wherein the preset parameter is a number of times the frequency-domain resource has been used by the terminal, and the selecting one or more idle frequency-domain resources among the idle frequency-domain resources based on a preset parameter comprises: selecting the frequency-domain resource that has been used and has been used for a highest number of times.
